Interesting discovery...
Well, I ran the test print on the "gold leaf" vinyl, and as you predicted Fred, it didn't get fully printed into the slight texture. However, it DID produce an interesting effect that would be the right touch in a given situation. The Edge printing on the gold leaf vinyl produces an effect that appears worn, maybe thinning from years of slight abrasions. In short, it looked like very very old gold window jobs I've seen - very antique appearance. Might be just the thing for next movie set job. haha
